Performance of camera-based vibration monitoring systems in input-output modal identification using shaker excitation
A complete dynamic characterisation of structures requires modal frequency, mode shape, modal damping and modal mass to be established for each mode. This can be achieved by using experimental modal analisis (EMA). EMA requires an input force and the resulting structural response to be measured. Optical vibration monitoring systems, enabling remote sensing, could make this process less challenging. This very issue was explored in our latest paper.
